MACHINE FOR TURNIN Gr SPOOLS.` i

i Speccation of Letters Patent No. 3,?710, dated August 21, 1844.

To all whom t may concern.'

Be it known `that LJoNATi-IAN H. CARY, of

North New Salem, in the county of Franklin and State of Massachusetts, have invented a certain new and `useful Machine for Making j Spools and Robbins, and that the following description and `accompanying drawings,

taken together, constitute a full and exact specification of the construction and opera through the axis of the bobbin, consists of Figure l of the said drawings represents a top view or ichnographic projection of the i machine. Fig. 2 is an elevation of the front g side thereof. Fig. 3 is anelevation of the l right hand end. Fig. 4 is a central and verg tical section taken looking toward the right. l A, Figs. l, 2, 3, 4: is a frame suitably conj structed for sustaining the operating parts. l A long drum B, is arranged horizontally tion of my invention.

within the lower posts of the frame, the said drum being revolved by a belt (from the driving power) which passes around the fast pulley of two pulleys C, D, arranged upon j one end of the shaftof the drum-or on the portion denoted by the drawings.

The top part of the frame has parallel rails a, b, placed upon it, the said rails serving to sustain, and guide movable puppet heads E, E, which are suitably connected together and rest upon them and carrying a mandrel F, to which the piece of wood from which the spools or bobbins are to be formed, is attached, the said mandrel being revolved by a bolt c, `which passes around the main driving drum, and a pulley d, on the mandrel. One end of the piece of wood from which the bo-bbins are to be turned, being iixed in the end of the mandrel the other end of it is brought up and borne against, or inserted within a circular aperture e, formed horizontally through the upper part of a puppet head G. A cutter f, (see Fig. 4) fixed within the side of the aperture reduces the stick (as it is revolved by the mandrel) to a, cylindricalform.

The operative applies his hand to a handle g, projecting from one of the puppet heads E, and draws or slides the puppet head, toward the right. This operation presses the piece of wood against the rounding cutter and causes it to enter and pass through the circular aperture e, (as fast as it is reduced) until it meets or comes in contact with the left side of a stop L, eX- tending from the circular saw carriage z'.

The remaining mechanism consists of that for boring the hole or passage through the axis of the bobbin, that for reducing the body of the same so as `to form the heads, and the space between them, on which the yarn is usually wound, and lastly that for` cutting olf or separating the bobbins from the stick `as fast as they are successively formed.

The mechanism for boring the hole which issupported (so as to slide to and ffro longitudinally) inthe upper end of two standards 2 7c, elevated vertically upon aA transverse frame Z, which acts uponthe rails a, b. Themandrel i has a rack m, of teeth `fitted to its lower side into which a sectoral upon a transverse shaft o, supported in bear-` ings j), Q. The front end of the shaft 0, has a handle s, extending at right angles from it as seen in Fig. 2. When this handle is raised into `a vertical position or thereabouts, the boring tool will be thrown back, or so that its cutting point shall not be in contact with the end of the stick of wood resting against the step it. But when the said handle is turned toward the left, or in a horizontal position the boring tool is driven against the wood, and as the wood revolves, bores a hole into the axis thereof, the length of which hole is equal to or a little greater than that of the bobbin. i i

The cutters for reducing the body of the bobbin `or forming the space between the heads thereof are shown at t, w, o, Fig. l.

,They are suitably confined by screws to a holder w, which at its end opposite to that to which the cutters are attached is jointed to vertical standards so as to admit the other end to play or move up and down in a vertical direction. A stud y, (see Fig. 4 and Fig. 5 which is a vertical section taken in a longitudinal direction through the rack or cam, bar a) projects from the side of the cutter holder w, and rests upon the top of a cam or inclined plane a', raised upon the rack bar a, as seen more particularly in Fig. 5. The said rack bar is supported in suitable bearings c, so as to slide to and fro longitudinally. It has a rack d, of teeth upon its underside which engages with a dle s, is turned down in order to cause the boring tool to advance toward the stick. The rack bar y, will be pressed forward and cause the cutting holder to descend, and thereby bring the cutters u, o, against the cylindric surface of the stick f so as to gradually reduce the saine, as the borer continues to advance. The cutter holder is drawn down with the requisite force to cause its cutters to perform their ofice by a spring g F ig. 4L, which is connected by a rod h3, to the cutter holder. The cutter holder is borne down upon the stick until it rests upon a stop 3.

A circular saw 7c, (supported on the left end of an arbor Z, and driven by means of a band m, which passes around the driving drum, and a pulley n on the arbor) is employed to cut off the spools or bobbins as fast as they are formed. It is arranged in the position as seen in the drawings and supported upon a horizontal frame 0', which is made capable of being moved forward and back so as to carry the saw toward and away from the stick. As soon as the operations of boring and turning are completed,

the handle s, is elevated, and the saw advancedtoward or against the work, so as to cut off a bobbin which drops downward and into `a'conductor 20', which carries it out of the machine. The right face of the saw is placed at a distance from the stop L equal vto the length of the bobbin, the cutters which remove the body part of the bobbin,

being arranged midway between the saw, and sto-p, as seen in the drawings.

The saw carriage may be thrown forward by a cam arranged on the under side of the rack bar a, which when the-handle s, is thrown back far enough will act against a projection from the saw carriage, and force the saw forward to a suiiicient degree for it to accomplish its purpose. The cutter carriage may be forced back by a spring or other proper contrivance suitably arranged.

Having thus described my improvement I shall claim y The machinery for sustaining the stick, and giving to it a cylindrical form, in combination with that for reducing the cylindric of the stick so as to formlthe body (of the spool or bobbin) or part on which the thread is wound, with that for cut-ting olf sections or parts of the stick of the length to form spools or bobbins; and with that for drilling or boring the hole through the axis of the stick or spools, the whole arranged and operating substantially as set forth.

In testimony that the foregoing is a true description of my said invention and iinprovement, I have hereto set my signature this 7 th day of March, in the year eighteen hundred and forty four.
